This is a generously sized, shallow tea bowl formed with a thin wall throughout. It features a powerful design with undulating rim and a tightly drawn body. The interior has a shallow tea pool, and while the foot is small and the rim is narrow—echoing the form of Chōjirō’s flat tea bowls—this piece fully demonstrates Ichinyu’s distinctive style. The glaze applied to the entire piece is not particularly smooth, and a vermilion glaze is visible from the exterior to the interior. On the underside of the box lid, Zuiryu-sai has inscribed “Black Flat Tea Bowl, Uncertain (Seal).” Very few examples remain housed in boxes bearing an inscription by the Omotesenke Grand Master during Ichinyu’s lifetime.
